Will adding 2 much oil hurt the motor? ?

Question

Say if your motor takes 4qts of oil, and u add 5. Will this do any harm?

Answer 1

It can cause your seals to leak. Just drain a little and be careful not to over-fill it again.

Answer 2

Overfilling and engine with oil is more dangerous then underfilling it.  Reason being is because when and engine is properly filled , lets say 4qts, there in only about a half an inch to an inch of space between the oil level and bottom of the crankshaft.  If you add too much oil, the crankshaft will hit the oil while its spinning and make the oil aerate (foam) and the foam is what will get pumped through the engine rather then the liquid oil.  So basically foam and air will be pumped through and both are disastrous to the engine.      

Answer 3

you can blow a main seal causing oil pressure to drop very quickly. but a single quart might not be enough to cause a problem. i have seen cars come into the shop filled to three times their normal capacity and they drove out with out a problem.

Answer 4

It will weaken the seal and gaskets because with to much oil there will be to much oil pressure.  The best thing to do is drain out the excess oil before it get expensive to fix.

Answer 5

it is not good for it, it may damage the seals

Answer 6

Yes, oil may spill through the dip stick(wat u pull to check oil) while the car is operating. its definately not a god practice. you should always check with your dealer to make sure the amount of oil the motor holds. Good Luck!

Answer 7

Probably not.

Not all the oil goes into the engine at once. There's an oil pan that temporarily stores the oil as it recirculates.

The danger is WAY overfilling the engine (like doubling the amount of oil). Then the oil level is too high, then the oil is beaten into a foam by the moving parts, and no longer circulates and lubricates. THEN your engine is in big trouble.  

Answer 8

i was always told adding to much will cause your car to leak oil.
